VENTED OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 358,811, dated March 1, 1887.

Application filed August 5, 1886. Serial No. 210,055. (No model.)

To aZZ whom it may concern.-

Be it known that I. ALBERT HALLOWELL, a citizen of the United States, residing at Low ell, in the county of Middlesex and State of Massachusetts, have invented a new and use ful Improvement in Vented Oil-Cans, of which the following is a specification.

My invention relates particularly to the venting apparatus of that class of oil-cans which are used for lubricating ordinary inachinery-such as is used in textile-factories; and its object is to provide a more satisfactory instrument for this purpose than has hitherto been available. I

My invention is illustrated in the accompanying drawings, in which Figure 1 is an elevation, partly in section, of an oiling-can, and which illustrates my invention; and Fig. 2 is a partial sectional elevation of a modified form of a portion of the oil-delivery spout and its support.

Similar referencenumbers refer to similar parts in both of the views.

This oil-can is intended to be so constructed that it may be either used by the ordinary unskilled laborers in factories, who have been found by long experienceto beunfit to be trusted with an oil-can whose deliveryspout may be easily removed, or by workmen who are known to be careful enough to refill their own oil-cans without wasting oil. For these reasons I pre fer to construct the oil-can as shown in Fig. 1,

where a thick case-hardened delivery-spout, 1, having an interior oil-passage which is narrowly contracted in a part thereof which is so placed, as shown, that the contracted passage cannot be readily tampered with, is screwed into the delivery-spout support 2. The said delivery-spout 1, as shown in Fig. 1, is of an ordinary construction,which I do not claim as of my invention, and engages with the support 2 by means of a tapering screw which is formed upon its outer surface at its base. port 2 is made up of the central spout-supporting hollow cylinder, 10, and the air-chamber cover 11. The said cover 11 is preferably provided with a drainage-groove, which surrounds the base of the delivery-spout 1, and the cylinder 10 is provided with a screw upon its outer surface, which engages with a screw- The sup thread which is cutwithin an aperture which is in the bottom of the mouth-piece 3, as shown. The mouth-piece 3 is preferably attached to the oil-reservoir at by being soldered to the top thereof, and it is sometimes provided with the drainage-groove 7 in its base surrounding the cylinder 10, although this groove is not' really necessary. From the bottom of the mouthpiece 3 the small air-hole 5 is made, leading from the interior of the said mouthpiece to the oil-reservoir, while another small airhole, 6, leads through the cover 11, as shown.

I prefer to provide the cover 11 with the downwardly extending hollow cylindrical shield 8, although this shield may be dispensed with sometimes. The purpose of the shield 8 is to prevent the airhole 6 from becoming clogged, when the can is reversed, by any oil which might accidentally be within the annular air-chamber,which is formed in the mouthpiece 3 when the parts are properly put to gether, as shown in Fig. 1, and also to prevent the said oil from escaping from the said air-chamber through the air-hole 6.

A modified form of the spout-support 2 is illustrated in Fig. 2, where the air-hole 6 is protected from the oil which might be in the oil-chamber by a depending pipe or nipple, 9, and a second ordinary form of delivery-spout substituted for that shown in Fig. 1..

Where this oil-can is to be used by untrust worthy laborers, it is intended that the spoutsupport shall be firmly screwed down upon the top of the mouth-piece with asuitable wrench, to which the said laborers shall not have access, and that the can shall be filled after removing the spout 1, the said spout being screwed into its place with a wrench after the can is filled. The can is thus protected, and must be refilled and kept in order bya suitable person selected for the purpose,who can readily obtain access to the interior of the air-chamber at all times with the aid of his wrench, in order to clean out the air-ho] es, if they should become clogged by thickened oil or other means.

When the can is to be refilled by the person who uses it, the spout 1 is intended to be firmly fastened into the support 2, which may be done in any convenient way, and the said support and attached spout removed and replaced with the fingers in the common way. In this case a packing-ring may surround the shield 8 and rest upon the top of the mouth-piece 3 in the usual manner, if so desired.

I prefer to so place the air-hole 6 in the spoutsupport that it shall not be directly above the air-hole 5, in which case oil might be thrown through the holes 5 and 6 when the can was suddenly reversed, but as far from directly above it as it can readily be placed, asv

shown in Fig. 1. The air-holes 5 and 6 are usually very small in diameter, unless the oil which is used is very thick and sluggish in its motion, the proper diameter depending, to a certain extent, upon the quality of the oil which is used.

I have in my invention dispensed with the usual air pipe which has been used in this class of oil-cans to conduct the airthrough the oil in the oil-reservoir 4, since I have found the said pipe to be productive of irregularity and the cover to the said mouth-piece that is perforated by the air-hole 6, substantially as described, and for the purposes specified.

2. The oil-can,which consists of the oil-reservoir, the mouth-piece 3, attached thereto and provided with the air hole and the screwthreaded aperture in its bottom, the deliveryspout, the support for the said spout having the hollow cylinder 10, which screws into the threaded aperture in the bottom of the said mouth-piece, the rigid cover to the said mouthpiece perforated by theair-hole 6, and the means, as set forth, for keeping any oil which might be within the said mouth-piece away from the said air-hole 6, substantially as described, and for the purposes specified.

3. The oil-can, which consists of the oil-reservoir, the mouth-piece 3, attached thereto and provided with the air-hole and the screwthreaded aperturein its bottom, the deliveryspout provided with an external and tapering screw-thread at its base, and the spout-support having the hollow cylinder 10, externally threaded at its base and internally threaded at its top, the cylindrical shield 8, the mouthpiece cover 11, and the airhole 6, protected by the said shield, substantially as described, and for the purposes specified.
